In the summer of 1976, engaged couple David Shuldees and Ellen Mathies were shot and killed at a remote campground in McClintock Park, Wisconsin. The vicious double homicide baffled investigators for decades, cycling through false leads, flawed blood-typing evidence, and even an erroneous evidence destruction order in 1980 that compromised key lab materials. The case finally broke in 2018 when genetic genealogy and DNA phenotyping led authorities to Raymond Van Evenhoven. Investigators matched his DNA to evidence from the crime scene, culminating in his 2019 arrest, 2021 conviction, and subsequent life sentence at age 85.
The podcast details the meticulous investigative steps that spanned over forty years, contrasting the typewriter-era police reports of the 1970s with modern familial DNA databases. Host Delia D'Ambra examines witness accounts, a suspect composite sketch, and Van Evenhoven's prior criminal history, raising chilling questions about whether other unsolved crimes in the region might be tied to him.
The episode opens with a brief promotional segment for SimpliSafe home security, setting the tone before diving into the true crime story.
Delia introduces the double homicide at McClintock Park, outlining the initial shock and the time span between crime and justice.
The narrative details the discovery of David and Ellen, the forensic evidence collected, and the early investigative findings.
The chapter covers the decades‑long cold case, the evolution of DNA testing, and the eventual identification of a suspect through genetic genealogy.
Witness testimonies, including the gunshot report and the sighting of a rifle‑toting man, shape the early suspect profile.
The legal proceedings culminate with Raymond Van Evenhoven’s conviction, sentencing, and subsequent death in prison, closing the case’s official chapter.
Delia reflects on the lingering mysteries, potential additional victims, and the broader implications of the case.
Discovery of the Crime Scenestory
A staff member at McClintock Park found David Shuldees shot to death on a dirt trail near the campground on July 9, 1976.
Finding the Second Victimstory
Search teams discovered the body of Ellen Mathies in a field several hundred yards away from David the morning after the murders.
Two men on a joyride reported hearing a sharp rifle gunshot and later spotted a mysterious man walking quickly through the woods.
Flawed Blood Testing Errordata
A crime lab technician admitted to omitting a crucial blood test in 1976, rendering previous blood-typing conclusions completely untrustworthy.
Baffling Evidence Destruction Orderinsight
The chief deputy who expressed frustration over the stalled case signed an order in 1980 allowing the state crime lab to destroy key physical evidence.
Surreptitious DNA Collectionstrategy
Authorities covertly obtained DNA from Raymond Van Evenhoven by having an officer pose as a survey taker and asking him to seal his answers in an envelope.
“The real cost of a break-in isn't your valuables. It's the feeling that your home stopped being safe.”
“I was able to obtain the entire public investigative file for this crime. And as I started reading, it was like looking into a time capsule.”
“The pathologist found sperm present, which of course, he made sure to swab and preserve.”
“He told Fox 11, quote, "This is no longer an artist conjecture based on what some witnesses are telling them in a sit-down interview. This is science at work," end quote.”
In July 1976, a young couple camping in a Wisconsin state park were both shot dead. For forty years, investigators had a sketch, a plate number, a blood type — and not enough DNA to test. The investigation would span decades until the truth eventually surfaced. View source material and photos for this episode at: parkpredators.com/the-decades
